LDSlicer

Linked Data Slicer

Run LDSlicer

Currently LDSlicer supports only slicing from SPARQL Endpoints.

$ git clone https://github.com/keme686/LDSlicer.git
$ cd LDSlicer 
$ mvn assembly:assembly -DdescriptorId=jar-with-dependencies

Then run the following to slice your endpoint:

java -cp target/LDSlicer-0.0.1-SNAPSHOT-jar-with-dependencies.jar de.unibonn.iai.eis.slicer.Main  [ENDPOINT] [QUERY-CONSTRUCT] [OUTPUT] [FORMAT]

Example

To extract all restaurants from DBpedia endpoint run the following:

$ java -cp target/LDSlicer-0.0.1-SNAPSHOT-jar-with-dependencies.jar de.unibonn.iai.eis.slicer.Main  http://dbpedia.org/sparql "CONSTRUCT {?s ?p ?o} WHERE {?s a <http://dbpedia.org/ontology/Restaurant>. ?s ?p ?o}"  ./restaurants.nt NT

This command will start slicing process by rungin the slice query:

CONSTRUCT {?s ?p ?o} 
WHERE {
      ?s a <http://dbpedia.org/ontology/Restaurant>. 
      ?s ?p ?o
      }

Output file name will be restaurants.nt and output format in NT - N-Triples. The following output format parameters are allowed:

NT
TTL
RDF/XML
RDF/JSON
JSONLD
